What is the role of hydroxide ions in showing basic properties?
Answer and explanation
Correct answer: They give basic nature
The governing concept is the ionisation of bases in water. A soluble base such as sodium hydroxide dissociates to produce Na⁺ and OH⁻ ions, and the presence of OH⁻ gives the solution its basic properties, such as turning red litmus blue. Therefore option A is correct. Hydrogen ions are associated with acidity, while hydroxide ions do not form metals or carbon dioxide in this context.
